Angular contact ball-bearing cage with lubricant pockets

摘要

A window-type cage for an angular contact ball bearing. Lubricant pockets are provided in the spherical pocket surfaces which are provided for guiding the balls. These lubricant pockets are all arranged in regions which lie outside the bearing points between the ball and the cage in both the circumferential direction and the axial direction, such that the wall thickness of the cage at the bearing points is not reduced by the position and design of the lubricant pockets.
